The speaker 810 of the navigation system 200 may be integrated with the speaker 560 provided in the travel point guide device 100.

(Road link concept)
Here, as described above, the travel point guide apparatus 100 according to the present invention is characterized in that attention is paid to the road links constituting the road on which the vehicle travels. For this reason, below, the concept of this road link is demonstrated easily. FIG. 2 is a schematic diagram showing a vehicle traveling on the road toward the registration point P and the position of the registration point P set as the registration point. That is, in the navigation system 200, the road map displayed on the monitor 800 (FIG. 1) represents an actual road by approximating a broken line by a series of a plurality of road links L _{1 to} L ₁₁ , and a branch point on the road map. Is represented by a node.

In other words, a road link is a line segment that constitutes a polygonal line that approximates a real road by a polygonal line (both ends of the road link are nodes), and a line segment that has an inflection point or an intersection of the actual road as its ends. It is shown that. In the present invention, the information on the road link by the road on which the vehicle travels is compared with the road links L _{1 to} L ₁₁ leading to the registration point P registered in advance, and the vehicle travels when they match. Assuming that the registration point P exists on the extension line on the road, notification is made by voice.

(Registration operation for registration point P)
Next, the registration operation of the registration point P set in advance as a registration point will be described. FIG. 3 shows an example of the registration point setting screen 805 displayed on the monitor 800 (FIG. 1). As shown in FIG. 3, the registration of the registration point P is registered on the monitor 800. It can be performed by a panel touch operation according to 805. The registered point setting screen 805 can be displayed by selection on a menu screen (not shown) of the navigation system 200.

  As shown in the figure, the registration point setting screen 805 expands details such as a detail button 806 for displaying details such as road conditions, a point registration setting button 807 for setting a registration point P at a predetermined position, and road conditions. And a wide area display button 808 for displaying, and by depressing (ON) the location registration setting button 807, the current position where the vehicle is traveling, the traveling direction of the vehicle, the road link that is map-matched, The position of the vehicle on the road link can be displayed, and the registration point P can be marked (set) on the road.

  Specifically, when the location registration setting button 807 is pressed (ON), the direction of the registration location P and the notification when the vehicle approaches the registration location P are associated with the information of the road link on which the vehicle is currently traveling. The predetermined audio information is registered simultaneously. In practice, the registration point P is set by a setting operation using the operation unit 620 (FIG. 1).

(Travel point guide processing by the travel point guide device 100)
Next, details of the travel point guidance process according to the first embodiment will be described with reference to the flowcharts of FIGS. 4 and 5. FIG. 4 is a schematic diagram for explaining the positions of the two vehicles 10 and 20 traveling on the roads 30 and 40 having different traveling directions and the registration point P set as the registration points. FIG. 5 shows a processing procedure of travel point guidance for guiding the vehicle 10 (20) to the registration point P performed by the travel point guidance control unit 350 (FIG. 1). In the following description, the road 30, the configuration of the road link L ₁ ~L _5, the road 40 is displayed respectively by the configuration of the road link _L'1 ~L' _5, a road 30 where the vehicle 10 travels A description will be given assuming that the registration point P exists in the vicinity position. It shows that the vehicle 20 is traveling on the road 40.

  That is, as shown in the flowchart of FIG. 5, first, a travel position determination process for determining the travel position of a vehicle traveling on the road 30 (40) is performed (step S110). Next, the travel position acquisition unit 311 and the travel position determination unit 312 (FIG. 1) determine whether the vehicle traveling on the road has approached the registration point P (step S120), and the vehicle is registered by the determination in step S120. If it is determined that the vehicle has approached the point P (Yes at Step S120), the process proceeds to a road link acquisition process for acquiring information on the road link on which the vehicle is traveling, and the corresponding road link information is acquired ( Step S130).

  Next, based on the road link information acquired by the road link acquisition process in step S130, the process proceeds to the road link determination process (step S140), and it is determined whether the vehicle is traveling on the road link leading to the registration point P. Perform (step S150).

  Specifically, the road link information stored at the time of registration of the registration point P by the travel position registration unit 351 (FIG. 1) and the road link information on which the vehicle is currently traveling are collated, and both road links are obtained. When the information is the same, it is determined that the vehicle is traveling on a road link leading to the registration point P. That is, the determination process of step S150 is a process of determining whether or not the registration point P can be reached within a predetermined distance from the position where the vehicle approaches the registration point P.

  If it is determined in step S150 that the road link information on which the vehicle is traveling is the same (Yes in step S150), the process proceeds to a voice notification process and a voice notification process is performed ( Step S160). Specifically, it notifies the driver who drives the vehicle that the registration point P is approaching as a sound notification (step S170). That is, the notification by the voice can surely notify the driver of the vehicle that the registration point P has been approached.

  On the other hand, if it is determined in step S150 that the vehicle is not traveling on the road link leading to the registration point P (No in step S150), all the processes are completed without performing voice notification to the vehicle. (End).

Here, the processing procedure described above will be specifically described. As shown in FIG. 4, the registration point P exists in the vicinity of the road link L ₃ , and the vehicle 10 has road links L _{1 to} L that reach the registration point P. _{Since the} vehicle 10 is traveling on the road 30 that constitutes ₅ , the vehicle 10 can reach the registration point P within a predetermined distance. Thus, when the vehicle 10 approaches the registration point P, a predetermined sound (for example, a predetermined pseudo sound or “approaching the registration point P”) is notified from the speakers 560 and 810. On the other hand, since the vehicle 20 is traveling on the road 40 constituting the road link, the vehicle 20 does not reach the registration point P even after following the road links L ′ _{1 to} L ′ ₅ on the road 40 (registration point). In order to reach P, a predetermined distance or more is required), and predetermined sound is not notified from the speakers 560 and 810 to the vehicle 20.

  As described above, according to the first embodiment, it is determined whether the road link on which the vehicle travels is the same as the road link at the time of registration, and the vehicle is traveling on the road link at the time of registration. In addition, when approaching the position of the registration point P set in advance as a registration point, a voice notification indicating that the registration point P has been approached is performed, so that the registration point P registered in advance for the driver of the vehicle is It is possible to accurately and surely notify that the vehicle is traveling along the existing road link and that the vehicle is approaching the registration point P.

  In addition, according to the first embodiment, since the determination based on the road link is performed, the vehicle traveling on the road approaches the registration point P, but the vehicle traveling on a different road On the other hand, there is no mistaken voice notification.

(Processing procedure for travel point guidance by travel direction)
Next, with reference to the flowcharts of FIGS. 6 and 7, the details of the travel point guide process performed by the travel point guide control unit 350 (FIG. 1) according to the second embodiment will be described. FIG. 6 is a schematic diagram showing two vehicles 10 and 20 that run opposite to each other on the road and the positions of the registration points P. FIG. 7 shows a travel point guidance processing procedure for guiding the vehicle to the registration point P according to the travel direction in the travel point guide apparatus 100 according to the present invention.

  Here, the second embodiment corresponds to the case where the azimuth α of the registered registration point P is compared with the azimuth of the vehicle traveling on the road (the traveling direction of the vehicle) and the azimuths of the two coincide. It is characterized in that a notification is given by voice indicating that the registration point P is approaching the vehicle. More specifically, FIG. 6 shows both a vehicle traveling on the road from the α direction and a vehicle traveling from the β direction with respect to the registered registration point P. In this case, the α direction is The azimuth registered at the time of registration of the registration point P is the forward direction (the β direction opposite to the α direction is the reverse direction).

  Hereinafter, with reference to FIG. 6 and the flowchart of FIG. 7, the travel point guidance processing procedure based on the travel direction (direction) of the vehicle will be described. In the flowchart of FIG. 7, detailed description of the processing procedure similar to that of the flowchart of FIG. 5 described above is omitted, and a characteristic part related to the traveling direction determination processing is mainly described.

  That is, as shown in the flowchart of FIG. 7, first, in step S110, a travel position determination process for determining the travel position of the vehicle is performed, and it is determined whether the vehicle has approached the registration point P (step S120). If it is determined in S120 that the vehicle has approached the registration point P (Yes at Step S120), then a road link acquisition process is performed (Step S130), and then a road link determination process is performed (Step S140).

  And below, it transfers to a driving | running | working direction determination process (step S145). Specifically, it is determined whether the traveling direction of the vehicle coincides with the registered road link direction (step S146). The travel direction determination process in step S146 is a process of determining the travel direction of the vehicle traveling on the road by the travel direction determination unit 355 (FIG. 1). If the traveling directions coincide with each other in the determination in step S146 (Yes in step S146), the sound A is output from the speaker (step S147).

  On the other hand, if it is determined in step S146 that the traveling direction of the vehicle does not match the registered road link direction (No in step S146), the audio B is output from the speaker 810 (560) (step S148). Thereafter, the process ends (END).

  Here, in the second embodiment, when the driving directions are different, different sounds (voice A / voice B) are notified to the driver according to the driving directions. In this case, the voice A notified to the vehicle that matches the direction of the registered road link is, for example, “approaching the registration point P”, but the vehicle is directed in the direction opposite to the direction of the road link. On the other hand, for example, the voice indicates that the vehicle travels in the reverse direction, such as “approaching the registration point P from the reverse direction”. As will be described later, the sound (sound A and sound B) output from the speakers 560 and 810 can be changed as appropriate by the selection / setting of the sound selection screen 551 (FIG. 14) and the sound selection unit 540. .

  Here, the processing procedure according to the flowchart of FIG. 7 described above will be specifically described. The vehicle 10 is traveling in advance toward the registration point P in a direction that matches the direction of the road link to the registration point P. Therefore, when the vehicle 10 approaches the registration point P, a predetermined sound A (a predetermined pseudo sound or “approaching the registration point P” or the like) is notified from the speakers 560 and 810. On the other hand, since the vehicle 20 is traveling toward the registration point P from the direction opposite to the direction of the road link leading to the registration point P, the sound B (for example, from the speakers 560 and 810 to the vehicle 10) , “I am approaching from the opposite direction of the registration point P”).

  As described above, according to the second embodiment, when the azimuth α of the registration point P registered in advance is compared with the azimuth (traveling direction) of the vehicle traveling on the road, both azimuths coincide with each other. In addition, since a notification indicating that the registration point P has approached the corresponding vehicle is performed by voice, on the other hand, for a vehicle approaching from a different direction with respect to the registration point P, notification by another voice is performed. Appropriate travel guidance can be reliably given to both vehicles traveling on the road.

(Travel point guide processing procedure for curved roads)
Next, with reference to the flowcharts of FIGS. 8 and 9, the details of the travel point guidance process performed by the travel point guidance control unit 350 (FIG. 1) according to the third embodiment will be described. Here, FIG. 8 is a schematic diagram illustrating a vehicle traveling from a straight road toward a curved road and a position of a registered point P registered on the curved road. FIG. 9 shows a processing procedure of travel point guidance for a curved road that guides the vehicle to the registration point P in the travel point guide device 100 according to the present invention. In the following explanation, as shown in FIG. 9, it is assumed that there is a curved road ahead of a straight road on which the vehicle travels, and that a registration point P exists in the middle of the curved road.

  Here, in the third embodiment, a predetermined azimuth registered corresponding to the registration point P registered in advance on the curve road is compared with the azimuth of the vehicle traveling on the curve road from the straight road. Is characteristic in the process of travel point guidance for a curved road that performs a voice notification indicating that the registration point P is approaching the vehicle.

  More specifically, when the vehicle travels from a straight road via a road link on a curved road and is compared with an expected traveling direction when the vehicle arrives at the registration point P, A notification by voice indicating that the registration point P is approaching is performed. That is, by this, even if the registration position of the registration point P is a curved road, appropriate travel guidance can be performed.

  That is, as shown in the flowchart of FIG. 9, after the travel position determination process (step S110), the road link acquisition process (step S130), and the road link determination process (step S140) are sequentially performed, the distance determination in step S151 is performed. Transition to processing. This distance determination processing is performed by the distance determination unit 357 (FIG. 1). Specifically, the vehicle follows the road link registered when the registration point P is registered, and approaches the registration point P to a predetermined distance. It is determined whether or not it has been performed (step S152).

  If it is determined in step S152 that the vehicle has approached a predetermined distance from the registration point P (Yes in step S152), then the predicted traveling direction of the vehicle is the direction registered in the registration point P and It is determined whether or not they match (step S153). Specifically, when the vehicle travels on the road link shown in FIG. 7, it is determined whether the predicted traveling direction of the vehicle matches the direction registered at the registration point P. If it is determined in step S153 that the predicted traveling direction of the vehicle coincides with the direction registered in the registration point P (Yes in step S153), the process proceeds to a voice notification process (step S160). Hereinafter, predetermined audio is output from the speakers 560 and 810 (step S170).

  In the third embodiment, since it is assumed that there is a curved road ahead of the straight road on which the vehicle travels, as the sound to be notified to the driver of the vehicle, for example, “curve” There may be a registration point P on the road ", or it may be simply notified in advance of" There is a curve road ".

  As described above, according to the third embodiment, the predicted traveling direction when the vehicle arrives at the registration point P via the road link on the curved road from the straight road is compared, and the predicted traveling direction of the vehicle If the direction of the registration point P coincides with the vehicle, a voice notification that the registration point P is approaching the vehicle is made. Therefore, even if the registration position of the registration point P is a curved road, Thus, it is possible to reliably perform appropriate travel guidance.

(Traffic point guidance processing procedure by road type determination processing)
Next, with reference to the flowchart of FIG. 10, the detail of the travel point guidance process performed in the travel point guidance control part 350 (FIG. 1) which concerns on Example 4 is demonstrated.

  Here, in the fourth embodiment, the type of road on which the vehicle travels is determined, and the vehicle is registered at the registration point P according to the determined type of road (general road, highway, toll road, other road). It is characterized in that different audio information is notified when approaching.

  That is, as shown in the flowchart of FIG. 10, first, a road type determination process for determining the type of road on which the vehicle travels is performed (step S210). The road type determination processing in step S210 is performed by a road link type determination unit 358 (FIG. 1) that determines various road types based on road link information.

  Next, it is determined whether the traveling road on which the vehicle is traveling is a general road (step S220). If it is determined that the traveling road is not a general road (No in step S220), the next road type is determined. Transition to decision (highway). On the other hand, if it is determined in step S220 that the travel road is a general road (Yes in step S220), the audio A is output from the speakers 560 and 810 (step S225).

  In step S230, it is determined whether the traveling road is a highway (step S230). If it is determined that the traveling road is not a highway (No in step S230), the next road type determination ( Toll road). On the other hand, if it is determined in step S230 that the traveling road is an expressway (Yes in step S230), the speaker B 560 and 810 outputs the sound B (step S235).

  In step S240, it is determined whether the traveling road is a toll road (step S240). If it is determined in step S240 that the traveling road is a toll road (Yes in step S240), speakers 560 and 810 are used. Outputs a voice C (step S245). On the other hand, if it is determined in step S240 that the travel road is not a toll road (No in step S240), it is determined that the travel road is another road (step S250), and audio D is output from the speakers 560 and 810. In step S255, all processing ends (end).

  As described above, according to the fourth embodiment, the travel guidance for the registration point P is reliably performed, the road type on which the vehicle travels is determined, and the determined road type (general road, highway, Depending on the toll road and other roads, when the vehicle approaches the registration point P, different audio information is notified, so that the audio notification according to the type of road on which the vehicle is traveling can be appropriately performed. .

(Procedures for travel point guidance for the travel speed of the vehicle)
Next, with reference to the flowchart of FIG. 11 and FIG. 12, the details of the travel point guide process performed by the travel point guide control unit 350 (FIG. 1) according to the fifth embodiment will be described.

FIG. 12 is a schematic diagram showing the positional relationship (separation distance) between the vehicle and the registration point P. In FIG. 12, the separation distance between the vehicle and the registration point P is T, and the speed of the vehicle traveling on the road is V (km / h).

  Here, the fifth embodiment is characterized in that the sound type and the sound volume are varied and output according to the traveling speed of the vehicle. Specifically, the type of sound notified from the speaker 810 (560) when the vehicle is traveling above a predetermined speed set in advance and when traveling at a speed lower than the predetermined speed, The sound volume can be automatically changed. For example, silence can be avoided by using voice notification when the vehicle's running speed is determined to be fast, such as when there is a dangerous part ahead of a curved road, by silence. can do.

  That is, as shown in the flowchart of FIG. 11, first, the speed of the vehicle traveling on the road is acquired (step S310), and then the process proceeds to the vehicle speed determination process for the vehicle speed acquired in step S310. (Step S320). This vehicle speed determination process is a process for determining by comparing the vehicle speed acquired in step S310 with a preset vehicle speed.

  That is, it is determined whether or not the vehicle speed is equal to or higher than a predetermined vehicle speed (step S330), and whether or not the vehicle speed is equal to or higher than a predetermined speed (for example, 50 km / h or higher) is determined based on the determination in step S330 (step S330). ) If the vehicle speed is greater than or equal to the predetermined speed as determined in step S330 (Yes in step S330), the sound X is output from the speaker 810 (560) (step S340). On the other hand, if it is determined in step S330 that the vehicle speed is not equal to or higher than the predetermined speed (No in step S330), a sound Y different from the sound X is output from the speaker 810 (560) (step S350).

  Here, FIG. 13 shows a vehicle speed / distance table 815 showing the correlation between the vehicle speed (km / h) of the vehicle and the separation distance T. As shown in FIG. When the vehicle speed is less than 20 km / h, the distance is set to 50 m, when the vehicle speed is up to 40 km / h, the distance is set to 100 m, and when the vehicle speed is 40 km / h or more, the distance is set to 300 m. With reference to 815, the timing of the sound and volume notified to the vehicle is controlled.

  In this case, the separation distance T may be a linear distance or a distance based on a road link between points. That is, the timing for outputting (notifying) the guidance of the registration point P to the vehicle can be set according to the traveling speed of the vehicle and the interval (distance) between the vehicle and the registration point P.

  Here, when the vehicle approaches the registration point P, the voice notified from the speaker 560 (FIG. 1) can be variously set by the voice selection unit 540 (FIG. 1) having a function of switching and selecting voice data. Can be changed to voice. Specifically, as shown in FIG. 14, a voice selection screen 551 can be displayed on the monitor 800, and a predetermined voice can be set on the voice selection screen 551. That is, as shown in the figure, a plurality of types of audio data (audio A to audio F) or no audio data (when the no audio button 552 is pressed) can be appropriately selected and set as a predetermined audio type. it can.

  Note that the voice selection screen 551 shown in FIG. 14 indicates that “voice A” has been selected by pressing the registration button 553 (ON). In addition to the above-described audio types, it is possible to separately select and set whether or not to output audio and the sound volume (volume). Here, regarding the switching of the sound, a user may set so that a different sound can be selected for each registration point P. It should be noted that a predetermined default voice is automatically set when the voice type is not specified by the voice selection unit 540 and the voice selection screen 551.
